[SFDXA] U.S. Hams distribution

[Kai]

Hi John,
We can check that from the LOTW intro page. The average QSL rate is twice the  
"QSL records have resulted. divided by "QSO records have been entered into the 
system.", which works out to about 34%. So the average QSL rate for LOTW users 
is 34%.  In an older analysis, I convinced my self that the number of uploaded 
errors in the system was around 10-12%, so the actual rate would be around 38 to 
39%.

Divide that 0.38 into the 86470 users of LOTW and you get 228,000 hams that 
participate in the things that LOTW users like to do (except a lot of them don't 
QSL!!).
